Abstract

In this paper, study of effect of slop of non-prismatic beam on the values of fatigue load required of failure the non-prismatic beam and the location of failure of beam. The study presented, theoretical study of non-prismatic beam with dynamic fatigue load in bending effect on the non-prismatic beam. And the compare of analytical results with numerical results presented and given good agreement with maximum error about 2.8% and minimum error about 1.3%. The parameters study are the small to large diameter non-prismatic beam ratio, length to large diameter beam ratio, large diameter of beam , and the type of material using on the values of fatigue load, location of failure of beam, and fatigue stress applied to maximum fatigue stress of beam ratio and the location of maximum fatigue stress on non-prismatic beam. The length to large diameter ratio using from ' 10 to 100' and small to large diameter beam ratio using from ' 0 to 1 ' and the large beam diameters using are ' 5, 10, 20, 30, 40, 50, 75, 100, 150, 200, and, 250 mm'.
